Answer to Question #64961 in Other Biology for DD
What is the expected genotypic and phenotypic ratio expected for the progeny in the previous question?
Genotypes corresponding to black and white color are BB and Bb
Genotype corresponding to brown and white color is bb
As brown and white offspring were produced, both parents with black and white color must have the recessive allele
Thus, both parents have genotypes Bb.
So, the cross was the following:
P: Bb Bb
G: B and b B and b
F1: BB Bb Bb bb
The expected phenotypic ratio is 3 black and white : 1 brown and white
The genotypic ratio is 1 BB: 2 Bb: bb
